how do i solve this G(t)=4t+1 find the following G(2)=, G(10)=, G(6.9)=

g(2) = 4(2) + 1 = 9
just substitute the number in perinthases for t. 
given the function G(t)=4t+1 find each of the following G(2)=, G(10)=, G(6.9)= plz help me don't understand this

Subsitute the 2 for the t, and then the 10, then the 6.9 so you get:
g(2) = 4(2) + 1 = 9
g(10) = 4(10) + 1 = 39
g(6.9) = 4(6.9) + 1 = 28.6
